Interesting question, and one of the many delightful inconsistencies and questionable items in the Holmes canon. For instance, where was Pope's Court, how many Moriarty brothers were there and why were they all named James, is Dr. Watson's first name John or James, why was the swamp adder able to kill Dr. Roylott instantly, yet leave Miss Stoner alive enough to give the clue "Speckled Band", who was Mrs. Warren, where on Baker Street was Number 221, because in Holmes' day the street didn't run quite that long. And a real great conundrum, read "The Musgrave Ritual" and try to draw a map of the house and grounds as described in the ritual......the list goes on and on.<br><br>These stories are really great fun. I discovered them in my carefree teens after being a fan of Rathbone and Bruce in the movies on late night t.v., and still enjoy them now as a grandfather in my 50's. <br><br>Read them, enjoy them and grow old with them. They've been read and loved for a long, long time, and will be for a long, long time to come.<br>
